Also, who did your last oil change (if this has only occurred recently. There have been posts on here and i have experienced it first hand. It is not that easy to reach the oil filter so there have been issues of the filter not being tightened properly causing a leak.

I went to a jiffy lube (needed it done quick). They told me my main seals were leaking. When i brought to dealer, turned out to be the filter. Oil did splatter all over the place so now periodically i get that oil smell when i run the motor.
